if im put my route in onPressed they redirect me to '/home' in my ShellRoute (how they work, why they dont work like previous, idk.) its work thats all i need now. the part

onPressed: () {
            GoRouter.of(context).go('/home');
            //_onNextPressed();
          },

the Main.dart :

GoRouter router = GoRouter(
  initialLocation: isLanguageSet
      ? '/home'
      : '/firstPage',
  routes: [
    GoRoute(
      path: '/firstPage',
      builder: (context, state) => FirstPage(),
    ),
    ShellRoute(
      navigatorKey: GlobalKey<NavigatorState>(),
      builder: (context, state, child) {
        debugPrint("Building ShellRoute with path: ${state.uri}");
        int index = getIndexFromPath(state.uri.path);
        return CurveBar(initialIndex: index);
      },
      routes: [
        GoRoute(
          path: '/home',
          builder: (context, state) => HomePage(),
        ),
